Schedule of Pensions and Postretirement Plans

The effect on operations of the post-retirement medical plan is shown in the following table:

	Three Months Ended September 30,					Nine Months Ended September 30,
	2014			2013		2014			2013
Service cost for benefits earned	$	0.1		$	0.1	$	0.2		$	0.3
Interest cost on benefit obligation	0.4			0.6		1.3			1.9
Net amortization and deferral	(2.0		)	0.2		(5.9		)	0.7
Post-retirement medical plan (benefit) costs	$	(1.5	)	$	0.9	$	(4.4	)	$	2.9

In the first quarter of 2014, the Company made certain administrative changes to the Plan which resulted in an expected reduction in future post-retirement medical benefits. The resulting reduction to the post-retirement medical liability was inadvertently not recorded until the third quarter of 2014. As a result, an out of period adjustment of approximately $11.7 (after tax) was recorded to reduce the post-retirement medical liability and increase other comprehensive income. The Company concluded that the impact was not material to the current or prior periods.

The effect on operations for the Company Plan and the PEP is summarized as follows:

	Three Months Ended September 30,						Nine Months Ended September 30,
	2014			2013			2014			2013
Service cost for administrative expenses	$	0.8		$	0.7		$	2.5		$	1.9

Net amortization and deferral	1.6			2.3			5.0			8.3
